Abstract
BACKGROUND Surgical options in male patients with genital lichen sclerosus (LS) involving the anterior urethra still represent a challenging issue. OBJECTIVE To review the outcome of surgical treatment in patients with genital and urethral LS. DESIGN, SETTING, AND PARTICIPANTS Multicenter, international, retrospective, observational descriptive study performed in two specialized centers. Two hundred fifteen male patients underwent surgery for histologically proven genital LS involving the foreskin and/or the anterior urethra. INTERVENTION Circumcision (34 cases), meatotomy (15 cases), circumcision and meatotomy (8 cases), one-stage penile oral mucosal graft urethroplasty (8 cases), two-stage penile oral mucosal graft urethroplasty (15 cases), one-stage bulbar oral mucosal graft urethroplasty (88 cases), and definitive perineal urethrostomy (47 cases). MEASUREMENTS Primary outcome was considered a failure when any postoperative instrumentation was needed, including dilation, or when recurrence was diagnosed. RESULTS AND LIMITATIONS The average follow-up was 56 mo (range: 12-170 mo). Circumcision showed 100% success rate with no recurrence of the disease; meatotomy, 80% success rate; circumcision and meatotomy, 100% success rate; one-stage penile oral mucosal graft urethroplasty, 100% success rate; two-stage penile oral mucosal graft urethroplasty, 73% success rate; one-stage bulbar oral mucosal graft urethroplasty, 91% success rate; and definitive perineal urethrostomy, 72% success rate. Limitations include short follow-up for recording neoplastic degeneration and no instrument to investigate quality of life. CONCLUSIONS Patients with LS disease restricted to the foreskin and/or external urinary meatus showed a high surgery success rate. In patients with penile urethral strictures or panurethral strictures, the use of one-stage oral graft urethroplasty showed greater success than the staged procedures.

Abstract
Lichen sclerosus is an uncommon, chronic inflammatory skin disorder of unknown origin. It is clinically characterized by sclerotic, whitish, atrophic-type lesions. The most frequent site of the lesions is generally the genital region, with about 15-20% having additional extragenital involvement. We present the case of a 62-year-old woman with a very extensive extragenital lichen sclerosus who showed great clinical and subjective improvement with 0.1% tacrolimus ointment and psoralen plus UVA (PUVA), without any topical or systemic adverse effects. Combined treatment of 0.1% tacrolimus ointment and PUVA may be a good option in extensive cases of lichen sclerosus or when other treatment options have failed, and has a good tolerability and safety profile.

Abstract
Lichen sclerosus is a chronic mucocutaneous inflammatory condition affecting both adults and children in a bimodal age distribution. Children can present as young as 6 months of age but average around 5 years. Females present with vulvar itching, soreness, dysuria, or gastrointestinal complaints, while males tend to have difficulty retracting the foreskin leading to phimosis. On examination, white smooth atrophic plaques are found in the anogenital region with atrophy and possible distortion of anatomy. LS in children has been commonly misdiagnosed as sexual abuse, leading to delay in appropriate diagnosis and unnecessary turmoil for families. It is a chronic relapsing and remitting condition possibly due to autoimmunity. When evaluating patients, a complete history can help guide which patients may benefit from a systemic evaluation for autoimmune disease. Although some patients have spontaneous resolution during puberty, many do not. There is a significant risk of squamous cell carcinoma developing in genital LS in adults possibly from chronic inflammation, delay in diagnosis, and delay in appropriate treatment. The risk of squamous cell carcinoma in pediatric onset LS is undefined. It is also unclear if effective control of cutaneous inflammation can decrease the risk of malignant transformation. Treatment is aimed at decreasing symptoms and returning involved skin to its normal appearance. Relapses are common. Ultrapotent topical corticosteroids are first line for the treatment of LS and can be used intermittently for years for flares. Topical tacrolimus or pimecrolimus are also good treatment options at controlling inflammation. Patients need to be monitored every 6 to 12 months even when asymptomatic because of the potential for development of malignancy. Given the distressing nature of LS, support groups and a multidisciplinary approach are recommended.

Abstract
Hypomelanotic skin disorders are cutaneous pigmentary disorders characterized by a reduced melanin content in the skin that results in a lightening of the skin. Establishing the correct diagnosis for hypomelanotic skin disorders requires a good history, a detailed physical examination, the use of special lighting techniques, such as Wood's light, and sometimes a biopsy of the abnormally pigmented skin and the normally pigmented skin. This article focuses on the origin, clinical presentation, and diagnosis of acquired hypomelanotic skin disorders. An algorithm for the diagnostic approach to these hypomelanoses is given.

Abstract
Balanitis xerotica obliterans (BXO), first described by Stuhmer in 1928, is a chronic, progressive, atrophic, sclerosing process involving prepuce, glans and urethra. Its aetiology is unknown. After a short terminological excursus and a review of the aetiological hypothesis, we have focused on BXO in daily urological practice. We are here describing the clinical presentation and its differential diagnosis with premalignant and malignant lesions of the penis. We tried to define the relationship between BXO and squamous cell carcinoma of the penis. Particular attention was then cast on urethral stenosis. Finally, we focused on the treatment of BXO: corticosteroid local therapy as first line treatment or as adjuvant therapy after circumcision, surgical therapy including circumcision, laser therapy of the glans lesions, meatoplasty in the stenosis of the anterior urethra. We also stressed the need for histological examination of the preputial specimen for a correct follow-up and for medicolegal reasons.

Abstract
BACKGROUND Lichen sclerosus (LS) is a chronic inflammatory disease of skin and mucosal surfaces which is generally difficult to treat. OBJECTIVE We evaluated the efficacy of oral cyclosporine in refractory vulvar LS. METHODS Five patients with refractory vulvar LS were treated with oral cyclosporine (3-4 mg/kg/d) for 3 months. They were followed up on a monthly basis. RESULTS At the end of the treatment, the mean total symptom score regressed significantly and clinical findings such as erythema and erosion showed marked improvement. Mild adverse effects were seen in 3 patients. LIMITATIONS The patients did not give consent to rebiopsy at the end of the treatment. CONCLUSION Moderate dose of oral cyclosporine could be an effective alternative in the treatment of refractory vulvar LS.

Abstract
Granzyme B and perforin messenger RNA (mRNA) expression has been shown to be a specific in vivo activation marker for cytotoxic cells. The aim of this study was to assess the contribution of cell-mediated cytotoxicity in the pathogenesis of lichen sclerosus. In situ hybridization and immunohistochemistry were performed on serial tissue sections of lesional skin biopsies and normal skin as control. Immunohistochemical staining showed that the cellular infiltrate of diseased skin consisted predominantly of T cells (CD3+) and some B cells (CD20+). Among T cells CD4+ and CD8+ cells were found in about equal numbers. In normal skin samples perforin and granzyme B mRNA expressing cells were only rarely found. In contrast, in biopsies from diseased skin a high percentage of infiltrating cells expressed mRNA for perforin and granzyme B. The perforin and granzyme B expressing cells were found in the dermal infiltrate and intraepidermally in close proximity to keratinocytes suggesting in situ activation of these cells. These findings provide evidence that cell-mediated cytotoxicity plays a significant role in tissue destruction in lichen sclerosus.

Abstract
BACKGROUND Vulvar lichen sclerosus (LS), a poorly recognized chronic inflammatory skin disease, may represent a therapeutic challenge. Pimecrolimus cream 1% is a nonsteroidal, selective inflammatory cytokine inhibitor that has recently been indicated for some inflammatory cutaneous diseases. OBJECTIVE To investigate the efficacy, tolerability, and safety of 1% pimecrolimus cream therapy in postmenopausal women with LS. METHODS A total of 16 patients applied pimecrolimus cream 1% twice a day over the first 3 months and then as required. All the patients completed this study and were then followed up over the next 12 months. The symptoms and clinical appearance of the lesions in every subject were recorded before and after treatment using a severity scale. RESULTS Using pimecrolimus, most of the patients exhibited a significant improvement with respect to symptoms and the clinical appearance of the disease. After 3 months of treatment, complete remission was seen in 11 patients, partial remission in four, whereas one patient experienced no response at all. Over the subsequent 12 months of follow-up, 10 patients exhibited complete remission while five had partial remission. Four cases with complete remission experienced a few relapses during the follow-up period. Older patients and those with an advanced stage of the disease responded poorly. No significant side effects were observed. CONCLUSIONS Pimecrolimus cream 1% appears to be an effective and well-tolerated therapeutic alternative option in the treatment of early stage of vulvar LS. Pimecrolimus may reduce the incidence of flare ups, improve long-term disease control, and enhance the patients' quality of life, especially in postmenopausal women.

Abstract
Eleven patients with linear cutaneous lupus erythematosus following the lines of Blaschko have been previously reported in the literature. We describe a child with this entity following Blaschko lines on the trunk. The patient responded to oral hydroxychloroquine therapy combined with topical flurandrenolide tape resulting in resolution with atrophic scarring. The clinical and histological features of linear cutaneous lupus erythematosus are discussed and a review of the literature is presented.

Abstract
Extragenital lichen sclerosus (LS) is usually asymptomatic and appears as ivory- or porcelain-white macules, papules and plaques. It is most common on the neck, shoulders and upper portion of the trunk. To date, the linear form of extragenital LS corresponding to the lines of Blaschko on the trunk or limbs has been rarely reported. We describe a 25-year-old Korean woman with sequentially occurring lesions of extragenital LS confined to the face following the lines of Blaschko.

Abstract
OBJECTIVE To evaluate the long-term results after carbon dioxide laser treatment of lichen sclerosus. MATERIAL AND METHODS We evaluated 62 consecutive patients with histologically verified lichen sclerosus admitted between 1985 and 1991. All patients were treated with a carbon dioxide laser with an output of 15-20 W and a defocused beam. This treatment vaporized the macroscopically altered area of the glans penis. Phimosis and superficial meatal stenosis were treated at the same session. Fifty-three men were still alive in 2004, and we were able to contact 50 of them (94%). The patients were asked about recurrence of symptoms, any visible penile lesion and recurrence of meatal stenosis. All patients who reported symptoms were invited to visit the outpatient clinic for further examination. RESULTS The median follow-up time was 14 years. At follow-up, 40 patients (80%) had no local symptoms and no visible lesion. Ten patients had minor symptoms but only two required further treatment. CONCLUSION Long-term follow-up of carbon dioxide laser treatment of lichen sclerosus shows that the treatment is safe and gives good results.

Abstract
Chronic cutaneous graft-versus-host disease (GVHD) is classically divided into two major clinical categories--lichenoid and sclerodermoid. Although diffuse areas of sclerosis as in scleroderma characterize the more advanced stages of the sclerodermoid form, the initial circumscribed plaques would be more correctly described as morpheaform. Eosinophilic fasciitis (EF) (a fibrosing disorder related to deep morphea) and lichen sclerosus (LS) have also been reported as manifestations of sclerodermoid GVHD. However, these two presentations of GVHD have not been emphasized in the dermatologic literature. We describe 6 patients, all of whom developed LS and two of whom also developed EF in the context of chronic GVHD. Each patient presented clinically with hypopigmented plaques that exhibited wrinkling, scaling, and follicular plugging. These lesions demonstrated the classic histologic features of LS including epidermal atrophy; a subepidermal zone of pale-staining, homogenized collagen; and a bandlike lymphocytic infiltrate. Although all patients eventually developed morpheaform and/or sclerodermoid GVHD, LS was a prominent part of the initial presentation of chronic cutaneous GVHD in every case. The LS lesions tended to occur on the neck and upper to mid aspect of the trunk, whereas morpheaform lesions favored the lower aspect of the trunk. EF involved the extremities (sparing the hands and feet), and was characterized clinically by an acute onset of pain and edema followed by induration with a rippled appearance. This case series serves to expand the spectrum of sclerodermoid GVHD, with LS as the most superficial and EF as its deepest manifestation.

Abstract
PURPOSE In this observational descriptive study we reviewed the histology and the clinical records of 130 patients with LS involving the male genitalia to determine the presence of premalignant or malignant lesions. MATERIALS AND METHODS A total of 130 male patients (from 1991 to 2001) with genital LS were treated at our centers. Mean patient age at diagnosis was 42.5 years. In all patients with a clinical diagnosis of LS, the histology was reexamined to look for evidence of LS, applying strict histological criteria. All cases of histologically proven epithelial malignancy, namely SCC, VC and EQ, were reviewed to confirm the presence of neoplastic changes and ascertain the degree of SCC differentiation. RESULTS Of 130 men 11 (8.4%) with genital LS showed premalignant or malignant histopathological features including 7 (64%) with SCC, 2 (18%) with VC, 1 (9%) with EQ and 1 (9%) with SCC associated with VC. In 6 of 11 patients (55%) the histological study showed the presence of epithelial dysplasia. CONCLUSIONS Survival of patients with penile carcinoma depends on early diagnosis and treatment, and all patients with genital LS should be observed closely to detect the development of neoplastic or preneoplastic lesions as early as possible.

Abstract
The incidence of vulval cancer is rising, both in older women and those under 50 years of age. Vulval cancer has at least two types, one arising in association with lichen sclerosus (LS) and the other with vulval intraepithelial neoplasia (VIN). Recent pathological and aetiological descriptions are included, along with the latest description of VIN terminology. Prevention of and screening for vulval cancer will require greater understanding of why some women with LS and VIN are at greater risk: recent studies of molecular change might contribute to this. The use of vulval cytology and toluidine blue staining is described. Patient or vulval awareness may help but clinical features are non-specific. Prophylactic vaccination against HPV and campaigns against smoking may contribute in the future.

Abstract
UNLABELLED Penile cancer, while relatively rare in the western world, remains a disease with severe morbidity and mortality, not to mention significant psychological ramifications. Furthermore, the disease is observed with dramatically increased incidence in other parts of the world. A review of the literature has shown that the overwhelming majority of penile cancers are in situ or invasive squamous cell carcinomas, including a well-differentiated variant, verrucous carcinoma. Important predisposing factors are lack of circumcision, human papillomavirus infections, and penile lichen sclerosus, although other factors have occasionally been reported as well. Prevention, careful monitoring of patients at risk, and early diagnosis are essential to reduce the incidence of penile carcinoma and to provide a definitive cure. Public health measures, such as prophylactic use of circumcision, have proved successful but are controversial. Also, no standard therapeutic guidelines as to the best treatment strategy according to different stages, including efficacy of conservative nonsurgical modalities and indications for lymph nodal dissection, are available so far. It is common opinion that penile cancer is an emerging problem that deserves further investigations, and physicians, especially dermatologists, should be aware of this issue. LEARNING OBJECTIVE At the completion of this learning activity, participants should be familiar with penile carcinoma, its risk factors, its clinical and histologic presentation, and the treatments currently available for its management.

Abstract
Genital lichen sclerosus in women is a clinically and histologically well defined disease. In addition to the classical atrophic form, there is a hypertrophic variant, which is characterised histologically by squamous cell hyperplasia. The aetiology is unknown but an autoimmune pathogenesis seems most likely. Infectious or hormonal influences do not play a major role. We describe a squamous cell carcinoma of the vulva with a co-existing lichen sclerosus. This case raises again the question of a precancerous potential of lichen sclerosus. In the dermatological literature, only a few cases with association of lichen sclerosus and squamous cell carcinoma are known. This is in contrast to gynaecological literature, where a high number of squamous cell carcinomas has been described. Gynaecologists search for the histological findings of lichen sclerosus adjacent to squamous cell carcinoma. Such an attempt is not valid without the clinical signs of lichen sclerosus, so that indeed classical lichen sclerosus does not seem to be a precancerous lesion. On the other hand, the hypertrophic form of lichen sclerosus seems to be associated with squamous cell carcinoma in about 3-5% of case.

Abstract
BACKGROUND A review of the English literature since 1940 did not reveal a reported case of lichen sclerosus involving the vaginal mucosa. Diagnosis of lichen sclerosus involving the vagina must thus be a rare occurrence. CASE This report presents the findings on a 54-year-old white woman with a history of lichen sclerosus involving the vulva. She was found to have lichen sclerosus involving the vaginal mucosa extending to the posterior vaginal fornix. The patient was started on the use of topical clobetasol ointment 0.05% to the vulva to be used twice daily for 1 month, at bedtime for 2 months, and every other day for 3 months. At follow-up, the vulvar and vaginal lichen sclerosus was unchanged, but the patient was asymptomatic. She was using the clobetasol 1 to 2 times per week. CONCLUSION Lichen sclerosus involving the vagina is a rare occurrence. Each case must be assessed separately and therapy initiated accordingly in each circumstance. Biopsy must be performed in all cases to identify the disease process and rule out malignancy.

Abstract
BACKGROUND Lichen sclerosus (LS) is a rarely diagnosed, chronic inflammatory skin and mucosal condition. Its therapy is difficult and frequently not satisfactory. The data on photodynamic therapy (PDT) of vulva are promising but scanty. The aim of our study was to evaluate the therapeutic efficacy of photodynamic therapy in genital LS in women. METHODS Twenty-four patients with clinical and histopathological diagnosis of lichen sclerosus accompanied with chronic vulvar itching, lasting between 3 months and 11 years, with human papillomavirus (HPV), bacterial and mycotic infections excluded, received three to six PDT cycles (180J, 700mW/cm(2)) in 14 days long intervals. Simultaneously they received no topical corticosteroids. Photodynamic diagnosis (PDD) was conducted prior to therapy and 4 weeks after its completion. RESULTS In 17 patients, the itching ceased completely, in 6 women it decreased, in 1 patient the itching continued, none of the patients presented exacerbation of itching. PDD after completion of therapy revealed in 10 patients normal, green fluorescence of vulva and in 14 women pathological, red fluorescence, usually fainter than before PDT. CONCLUSION PDT is an effective therapeutic modality for chronic itching in lichen sclerosus.

Abstract
This prospective study was designed to address the incidence and clinical and histologic characteristics of balanitis xerotica obliterans in a large random pediatric population with phimosis. We investigated 1178 boys who presented consecutively with phimosis between 1991 and 2001. All patients who underwent complete circumcision and surgical specimens were typed histologically as early, intermediate, or late forms of this disorder or as nonspecific chronic inflammation. Patients with balanitis xerotica obliterans were controlled at 1, 6, and 12 months postoperatively, then yearly. Balanitis xerotica obliterans was found in 471 of the 1178 patients (40%), with the highest incidence in boys aged 9 to 11 years (76%). Secondary phimosis occurred in 93% of boys with balanitis xerotica obliterans and in 32% of those without the disorder. In six instances of balanitis xerotica obliterans, meatotomy and in one meatoplasty was performed, as well as circumcision. On histologic evaluation, we found 19% had early, 60% intermediate, and 21% late form of balanitis xerotica obliterans. Glanular lesions disappeared completely within 6 months in 229 out of 231 patients. Our data strongly suggest that the true incidence of childhood balanitis xerotica obliterans is higher than previously assumed. Its incidence peaks in the 9 to 11 years age group, in whom secondary phimosis was almost exclusively caused by balanitis xerotica obliterans.

Abstract
Lichen sclerosus et atrophicus is a chronic inflammatory disease that mainly affects women in the 5th decade. Although lichen sclerosus most often affects the anogenital region, it may occur in other cutaneous or mucosal sites. Increased fibroblast activity causes cutaneous sclerosis. Recent studies have identified lichen sclerosus as an autoantibody-mediated chronic inflammatory dermatosis. Autoantibodies against the extracellular matrix protein-1 are present in up to 80% of affected patients. In addition to the well-accepted therapy with potent corticosteroids, promising results have been obtained using calcineurin antagonists in the treatment of lichen sclerosus. Interdisciplinary management with regular monitoring can improve the clinical manifestations and quality of life.

Abstract
The treatment of sclerosing skin diseases [systemic sclerosis, localized scleroderma, lichen sclerosus et atrophicus, sclerodermoid graft-vs.-host disease, scleredema adultorum (Buschke), scleromyxedema and necrobiosis lipoidica] is difficult and remains a great challenge. Numerous treatments, some with potentially hazardous side effects, are currently used with only limited success. The introduction of phototherapy and photochemotherapy for sclerosing skin diseases has considerably enriched the therapeutic panel and proven useful in a number of sclerosing skin diseases especially in localized scleroderma. Two phototherapeutic modalitites are used for the treatment of sclerosing skin diseases, long-wave ultraviolet A and psoralen plus ultraviolet A (PUVA). This article reviews current knowledge about the application of phototherapy and photochemotherapy to various sclerosing skin disorders.

Abstract
Hematopoietic stem cell transplant (SCT) is considered standard therapy for a variety of malignant and nonmalignant diseases. Graft-versus-host disease (GVHD) still represents today a major complication of hematopoietic SCT. Two types of GVHD have traditionally been recognized on the basis of the time of onset following transplantation, distinct pathobiological pathways, and different clinical presentations. The acute form commonly breaks out 2 to 6 weeks after transplantation, affecting up to 60% of patients receiving allogeneic transplants from HLA identical donors. Transfer of immunocompetent donor T cells contained in the graft may undergo alloreactivity against recipient cells because of major or minor histocompatibility antigens disparities between the donor and the immunosuppressed host. Target specificity in acute GVHD involves preferential injury to epithelial surfaces of the skin and mucous membranes, biliary ducts of the liver, and crypts of the intestinal tract. Chronic GVHD affects approximately 30% to 80% of patients surviving 6 months or longer after stem cell transplantation and is the leading cause of nonrelapse deaths occurring more than 2 years after transplantation. Chronic GVHD is a multiorgan syndrome with clinical features suggesting some autoimmune diseases, and possibly both alloreactive and autoreactive T cell clones are involved in its pathophysiology. Although GVHD may convey beneficial graft-versus-leukemia/lymphoma effects, it also entails a significant risk of morbidity and mortality. Patients with mild GVHD need only minimal, if any, immunosuppressive treatment, whereas prognosis of patients with extensive disease or resistant to standard immunosuppressive treatment may be dismal. Early recognition of GVHD followed by prompt therapeutic intervention may prevent the progression to higher-grade disease and improve the outcome for patients receiving hematopoietic SCT.

Abstract
OBJECTIVES Strictures due to lichen sclerosus (LS) may affect the urethra as far proximally as the mid-bulb. For such strictures, a staged full-length repair is required and should use a nonpenile graft source such as buccal mucosa. Many cases occur in a population already accustomed to seated voiding, leading us to re-evaluate this approach and, in some circumstances, recommend definitive perineal urethrostomy alone. METHODS We reviewed the medical records and retrograde urethrograms of all patients undergoing surgery for LS at our facilities between January 1991 and June 2002. RESULTS A total of 63 patients, with an average age of 54.2 years, underwent surgery for LS stricture with an average follow-up of 38.5 months (range 4 to 117). Of the 63 patients, 19 underwent grafting in preparation for future reconstruction. Of these, 11 completed the second-stage repair, and 8 patients elected not to undergo the second stage of the repair, leaving a functional perineal urethrostomy. This led us to look more critically at definitive perineal urethrostomy alone for some patients. Parallel with the staged repairs, and subsequent to them, 44 patients underwent perineal urethrostomy alone. CONCLUSIONS The often extensive nature of LS, the prevailing philosophy that urethroplasty must use nonpenile skin, the limited availability of such sources, and the acceptance of many patients for seated voiding makes definitive perineal urethrostomy alone a viable treatment option. In all our cases, this satisfied patients' quality of life concerns, leaving the anterior urethra dry and amenable to future repair. Younger men desirous of penile voiding should still be considered for staged repair using current techniques.

Abstract
Background Lichen sclerosus is a chronic inflammatory disease with a predilection of the anogenital region. Because of the potential side effects of repeated local application of potent glucocorticosteroids, equally-effective, safer therapeutic options are required, especially in the treatment of children. Case presentations We report on the efficacy of twice-daily application of pimecrolimus 1% cream in four prepubertal girls (range of age: 4 to 9 years) who suffered from anogenital lichen sclerosus. After three to four-month treatment, all patients had almost complete clinical remission including relief from itch, pain and inflammation. Only minor improvement was observed for the white sclerotic lesions. No significant side effects have been observed. Conclusions Topical pimecrolimus appears to be an effective and safe treatment for children with anogenital lichen sclerosus. The clinical benefits observed in the four patient presented particularly include relief of pruritus, pain and inflammation. Vehicle-controlled studies on a larger number of patients are now warranted to substantiate our promising findings, and to investigate long-term efficacy and safety of topical pimecrolimus in anogenital lichen sclerosus.

Abstract
Lichenoid eruptions are quite common in children and can result from many different origins. In most instances the precise mechanism of disease is not known, although it is usually believed to be immunologic in nature. Certain disorders are common in children, whereas others more often affect the adult population. Lichen striatus, lichen nitidus, Gianotti-Crosti syndrome, and lichen spinulosus are examples of lichenoid lesions that are more common in children than adults. Distinguishing these diseases is necessary for prediction of the course of the eruption and for optimal management. In most cases, certain clinical characteristics enable the clinician to reach a diagnosis, whereas in other cases biopsy is required for a definitive answer. Many of these lesions are self-limited and only require symptomatic treatment, although corticosteroids can hasten resolution in certain disorders. Discontinuation of the medication is often sufficient for resolution of lichenoid drug eruptions.

Abstract
Although the precise aetiology of lichen sclerosus is unknown, evidence for an autoimmune basis to the disorder is emerging. Indeed, circulating IgG autoantibodies to the glycoprotein extracellular matrix protein 1 (ECM1) have been demonstrated in the sera of about 75% of affected individuals. To assess this humoral immune response further, immunoblotting was performed using bacterial recombinant proteins spanning different domains of the ECM1 protein. The aim was to identify autoantibody-reactive sites recognized by 90 lichen sclerosus sera. The subclass distribution of anti-ECM1 IgG autoantibodies was also determined in 54 lichen sclerosus sera. Immunoblotting showed that the IgG autoantibodies from lichen sclerosus patients recognize multiple antigenic reactive sites on the ECM1 protein within both the amino terminus (50/90, 55.6%) and the protein loop cysteine-rich repeat domains (54/90, 60%), although few sera (7/90, 7.8%) had antibodies to the carboxyl terminus of ECM1. IgG subclass analysis revealed that the anti-ECM1 autoantibodies belong predominantly to the IgG(2) subclass (48/54, 88.9%), either IgG(2) alone (28/54, 51.9%) or in combination with one or more other IgG subclasses. No correlation was found between the site(s) of the ECM1 epitopes or the anti-ECM1 IgG profile and any specific clinical parameters. Nevertheless, characterization of anti-ECM1 antibodies does provide further insight into humoral immune responses and understanding disease mechanisms in lichen sclerosus.

Abstract
We present 10 cases of well-differentiated, squamous cell carcinoma of the penis with pseudohyperplastic features. At presentation, the median age was 69 years. Seven of the tumors were multicentric, and the majority preferentially involved the foreskin inner mucosal surface. Grossly the tumors were typically flat or slightly elevated, white and granular, and measured approximately 2 cm. Characteristic histologic features included keratinizing nests of squamous cells with minimal atypia surrounded by a reactive fibrous stroma. In biopsies or individual areas of resected specimens, the differential diagnosis with pseudoepitheliomatous hyperplasia was difficult but when samples of adequate size were available, obvious evidence of infiltration was present. The adjacent squamous epithelium typically showed changes that are known to be associated with squamous cell carcinoma ranging from squamous hyperplasia to low-grade, and in a few cases high-grade, squamous intraepithelial lesions. Well-developed lichen sclerosus was seen in all cases. Patients were treated by circumcision or partial penectomy. With the exception of 1 patient who developed a glans recurrence 2 years after initial circumcision, follow-up after the initial surgical procedure has been uneventful. The majority of penile carcinomas with the high degree of differentiation seen in these cases are in the category of the verruciform tumors, either the verrucous or papillary carcinoma, not otherwise-specified subtypes. Experience with the cases reported in this series indicates that a subset of nonverruciform, often multicentric, tumors with a high degree of differentiation and pseudohyperplastic features occur and preferentially involve the foreskin. Because it was present in all cases, lichen sclerosus may play a precancerous role.

Abstract
Malignant melanoma of the vulva in childhood is a rare neoplasm. Lichen sclerosus of the vulva in childhood is also a rare disease. The association of these two rare lesions in the vulva of young girls is extremely rare. We present a 10-year-old white girl with malignant melanoma associated with lichen sclerosus of the vulva. She had dark pigmentation of both the labia minora and posterior fourchette. The inner labia majora and fourchette showed whitish, glistening areas of skin. Histologic examination found mostly an in situ lentiginous/mucosal melanoma with focal invasion to a depth of 0.44 mm in the left upper labium majus. All specimens showed evidence of lichen sclerosus. Partial vulvectomy was performed, and no metastases were detected at the time of treatment. The patient has been disease free for the 12 months after treatment. It is critical for physicians to realize that melanoma can occur in children, and although rare, can occur in the vulva. We feel that lichen sclerosus in this instance may represent a pattern of host immune response to melanoma.

Abstract
Lichen sclerosus is a common, acquired chronic inflammatory skin disease of unknown etiology, although circulating autoantibodies to the glycoprotein extracellular matrix protein 1 (ECM1) have been detected in most patients' sera. We have examined the nature of ECM1 epitopes in lichen sclerosus sera, developed an ELISA system for serologic diagnosis, and assessed clinicopathological correlation between ELISA titer and disease. Epitope-mapping studies revealed that lichen sclerosus sera most frequently recognized the distal second tandem repeat domain and carboxyl-terminus of ECM1. We analyzed serum autoantibody reactivity against this immunodominant epitope in 413 individuals (95 subjects with lichen sclerosus, 161 normal control subjects, and 157 subjects with other autoimmune basement membrane or sclerosing diseases). The ELISA assay was highly sensitive; 76 of 95 lichen sclerosus patients (80.0%) exhibited IgG reactivity. It was also highly specific (93.7%) in discriminating between lichen sclerosus and other disease/control sera. Higher anti-ECM1 titers also correlated with more longstanding and refractory disease and cases complicated by squamous cell carcinoma. Furthermore, passive transfer of affinity-purified patient IgG reproduced some histologic and immunopathologic features of lichen sclerosus skin. This new ELISA is valuable for the accurate detection and quantification of anti-ECM1 autoantibodies. Moreover, the values may have clinical significance in patients with lichen sclerosus.

Abstract
A 52-year-old woman presented with an 18-month history of genital and extragenital lichen sclerosus. In addition to the classical genital findings, lesions of lichen sclerosus were present over her back, chest and the medial aspect of her right thigh and leg. On her right thigh and extending to her right leg, lesions of lichen sclerosus displaying the Köbner response were noted over the course of a varicosed long saphenous vein. There were no features of varicose dermatitis in the region displaying the Köbner response. It is proposed that the ambulatory venous pressure within the vein acted as a stimulus for the Köbner response.

Abstract
The aim of the study was to compare alterations of various regions of the basement membrane zone (BMZ) in lichen sclerosus (LS) using laser scanning confocal microscopy. The study included three cases of bullous LS, one case of bullous LS that developed in the course of graft-versus-host disease (GVHD), and six cases of non-bullous LS. Three cases of morphea served as a control. Biopsies from patients' skin and control biopsies from normal human skin were cut into 30-microm thick slides and labeled with antibodies against beta4-intergin (lamina lucida marker), collagen IV, and the N-terminal end of collagen VII (lamina densa markers) and the C-terminal end of collagen VII (sublamina densa marker) using routine immunofluorescence (IF). Three-dimensional (3D) reconstruction of various regions of the BMZ showed a decrease in the number and size of the dermal papillae in LS and morphea as compared with normal skin. In LS numerous invaginations and holes were present in the BMZ at the level of the lamina lucida and lamina densa. Computer animation of 3D projections revealed that the thickness of the lamina densa observed under the light microscopy is an optical artifact dependent on periodical tortion of the lamina densa along its axis. Torsions and invaginations of the BMZ are equally responsible for the phenomenon of artificial reduplication of the lamina densa observed at the ultrastructural level. IF labeling with antibody against the N-terminal end of collagen VII disclosed the presence of a large hole (up to 25 microm) in the lamina densa and the presence of granular material in deep dermis suggestive of partial degradation of lamina densa at the level of anchoring fibers. An IF mapping study showed blister formation below the lamina densa in three patients with bullous LS, whereas in a case of LS associated with GVHD, a blister formed through the basal layer of the epidermis. In morphea, there was flattening of BMZ at the level of lamina lucida, lamina densa, and sublamina densa but the continuity of BMZ was preserved. Three-dimensional reconstruction of dermal-epidermal junction in LS revealed alterations of the BMZ, most pronounced at the level of the lamina densa and sublamina densa.

Abstract
Certain dermatologic lesions may initially present or be more commonly ascribed to the elderly. These disorders encompass a diverse array of etiologically unrelated degenerative, autoimmune, idiopathic, and neoplastic conditions that may dramatically impact the quality of life and produce significant morbidity and mortality. As the population ages, a more complete understanding of the clinical and histopathologic features unique to the geriatric dermatologic patient is essential.

Abstract
Non-neoplastic epithelial lesions of the vulva (NNEDV) lichen sclerosus (LS) and squamous hyperplasia (SH) have been implicated in the pathogenesis of squamous cell carcinoma of the vulva (SCC). To date, there have been no recognisable precursor lesions for SCC associated with NNEDV. TP53 is the most frequent genetic change in human cancers and can indicate both aetiology and molecular pathogenesis of tumours. A total of 27 SCC patients underwent immunohistochemistry (IHC) and TP53 mutational analysis using microdissection and direct sequencing. There were 19 patients with areas of adjacent epidermis: 17 had NNEDV (four SCCs had more than one adjacent lesion) and two had normal epidermis. In all, 70.4% of the SCCs, 40% LS and 22.2% SH demonstrated overexpression of p53. In total, 77.8% of SCCs, 46.7% of LS and 22.2% SH demonstrated mutations in TP53, with the majority of lesions having a mutation in codon 136. Eight cases were identified where the same mutation was identified in the SCC and in the adjacent area. These data suggest that TP53 mutations develop in NNEDV and are intrinsic to the clonal evolution that leads to SCC. The type of mutation detected is more likely to occur due to endogenous cellular changes rather than exogenous carcinogen exposure.

Abstract
We describe a 21-year-old male patient with linear extragenital lichen sclerosus. The lesions are confined to the left side of his body and consist of 3 long bands running along the left leg and several patchy and linear lesions on the left side of his trunk. An associated finding is a smaller diameter of the distal part of his left lower leg caused by bony atrophy of the underlying portion the tibia. This is the fifth reported case of linear lichen sclerosus.
